2003 Dodge Grand Caravan Question: crunching noise on passengers side

I hear a crunching noise from seems to be the front wheel on the passengers side and I had it checked out by a mechanic but he said brakes,cv,and bearings are ok. I hear the noise intermitantly and more at low speeds,its been a crunching and squeeking sound.The van has 42000 miles on it and otherwise is in excellent shape ,has 3.3 engine.
